bloomberg, and others who don't get recognition. the average person out there is generous, i think. they want to be philanthropic but can't give a lot. if someone out there can afford to give $10 to any cause, where would you want them to send it? >> there are a lot of wonderful choices. there's one called donors choose where teachers put up projects and those are for small amounts of money. you go to that website you can help fund a thing that a teacher is trying to do with their class. can you go to save the children. they help mothers have safe births. you can go to the polio vaccination website t takes donations of any size. you can be sure that these organizations will put your money to good use. >> we talk a lot about the progress that you are achieving here. can you compare for me, though, the feeling you get today from being able to give away millions and billions of dollars to the feeling you had as a young man, being able to make your first million dollars? there's no crime in looking back and saying, boy, that was fun. co
